TRUSS-HOOP.

SPECIFICATION forming part of Letters Patent No. 409,241, dated August 20, 1889. Application filed March 5, 1889. Serial No. 301,871. (No model.)

To all whom it may concern.-

Be it known that I, LAWRENCE ROTH, a citizen of the United States, residing at Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Truss-Hoops for Oooperage, of which the following is a specification, reference being had to the accompanying drawings.

Figure 1 is a side view of the improved truss-hoop. Fig. 2 is a section of the same. Fig. 3 is the hoop, seen from above. Fig. 4c is an enlarged section, same as I), Fig. 2, showing the form of bar of which thehoop is made.

Similar letters in the several drawings denote the same parts.

The hoop is made of metal of the usual M thickness and taper, but differs from those heretofore used in having the upper and inner part cut away, as shown at 6, so as to make the upper inner diameter greater than the diameter a little below the top.

The object of the invention is to avoid the battering in hammering on the hoop of the upper and inner edge of the hoop.

Operation: This hoop is placed around the staves of a barrel or other similar article in process of construction precisely as it has heretofore been, to draw the staves together and confine them until the permanent hoop is applied. It is driven down upon the staves for that purpose by a hammer, and on account of the upper and inner part of the hoop being beveled off, as described, the breaking of the edge of the hoop that follows prolonged use is outward and does not cause the upper and inner edge to turn inward against the staves. All hoops heretofore used have their edges battered inwardly, thus reducing their diameter and cutting into the wood.

The hoop shown in the drawings has its lower edge also beveled. This beveling is useful, and although itis my invention I do not desire to secure it by patent now, and do not claim it now.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

A tapering truss-hoop having the upper inner edge cut away or beveled off, as shown, as and for the purpose set forth.

The foregoing specification of my invention signed by me this 9th day of February, A. D. 1889.

LAVVRENOE ROTH.
